Chemical Structure

Fluconazole EP Impurity F CAS 118689-07-9 chemical structure

Description

Structurally, Fluconazole EP Impurity F (C11H11F2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 255.22 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Fluconazole EP Impurity F (CAS 118689-07-9) is a certified pharmaceutical impurity reference standard with the molecular formula C11H11F2N3O2 and a molecular weight of 255.22 g/mol.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
